A seal ring for a charge air hose is a sealing component used at the connection points of the turbocharged air intake system. Its function is to ensure an airtight seal, preventing boost pressure leaks and maintaining proper engine performance.
Key specifications include inner and outer diameter, thickness, material (such as heat- and pressure-resistant rubber or silicone), temperature resistance, and compatibility with the turbo system. It must withstand boost pressure and high temperatures.
Replacement is necessary when the seal is worn, cracked, hardened, or leaking. Common symptoms include loss of engine power, hissing noises, or reduced turbo efficiency.
